“execgraph” leads to keyboard input delay and missing?

[LeMonMonOTS]

Background

I want to use conky to monitor and plot graphs for cpu tempterure, cpu ppt and fans speed. But it seems not to provide Variables to do this directly.

So I head for exec sensors | grep to do this:

# CPU TEMPREATURE
${offset 15}${font Entopia:bold:size=11}${color}CPU Temperature: ${exec sensors | grep 'CPU' | awk '{print $2 $3}'}
${offset 15}${execgraph "exec sensors | grep 'CPU'| awk '{print $2/85}'" 26,400 FFFAFA FF7878 1 -t -l}
# CPU PPT
${offset 15}${font Entopia:bold:size=11}${color}CPU PPT: ${exec sensors | grep 'PPT' | awk '{print $2 $3}'}
${offset 15}${execgraph "exec sensors | grep 'PPT'| awk '{print $2/25}'" 26,400 FFFAFA FF7878 1 -t -l}
# FANS SPEEDS
${offset 15}${font Entopia:bold:size=11}${color}Fan 1 Speed: ${exec sensors | grep 'fan1' | awk '{print $2}'}rpm  ${alignr}  Fan 2 Speed: ${exec sensors | grep 'fan2' | awk '{print $2}'}rpm
${offset 15}${execgraph "exec sensors | grep 'fan1' | awk '{print $2/6800}'" 26,200 FFFAFA FF7878 1 -t -l} ${alignr} ${execgraph "exec sensors | grep 'fan2' | awk '{print $2/6800}'" 26,200 FFFAFA FF7878 1 -t -l}

The function seems to be done very well, but after conky running for a while, keyboard input is noticeably lost and delayed.

Hardware platform

ThinkPad-T14-Gen-1 with AMD Ryzen 7 PRO 4750U with Radeon Graphics (16).

Software version

I'm using Ubuntu 22.04.4 LTS x86_64 OS with 6.8.0-40-generic kernel and my conky version is 1.12.2.

conky.conf

I hope it would be helpful although it is really messy:

This should look like this:

What I've tried to solve

1. I firstly wonder if update_interval is too small and the update is too frequent. So I've tried to set it bigger but keyboard input delay and missing just happened again a little later.
2. When I used top to check the resources taken by conky, I didn't see conky use too much cpu or memory. In fact I can hardly feel any performance issues other than keyboard input issues.
3. I've read exec will take a lot more resources than other variables. I doubt that if execgraph is also in this case. So I've tried to comment out the exec and execgraph related lines, this issue could be solved. Other graphs did work greatly.
4. I've also tried to replace execgraph with execigraph, and replace the "inline double-quotes" parameter followed by execgraph with bash script file version. But these all did't work.

Above these, I think this should caused by exec and execgraph (or execigraph). But I really have no idea how to improve performance while maintaining functionality.

Question

1. Is there a better way (not use exec or execgraph) to monitor and plot graphs for cpu tempterure, cpu ppt and fans speed with or without sensors?
2. What can I do to optimize the performance of exec and execgraph if possible?
3. If it is neccessary to start a issue for the new features of plotting the graphs of thermal stuff just like temperature, power and fan speed?
4. I also tried to increase "text_buffer_size=2048", but also not worked.

Thanks in advance for any help.

I just tried the latest v1.21.6 but the keyboard issue still exsited.
